35.220.20 - Magnetic storage devices in general

ISO/IEC 20919:2016 defines the LTFS Format requirements for interchanged media that claims LTFS compliance. Those requirements are specified as the size and sequence of data blocks and file marks on the media, the content and form of special data constructs (the LTFS Label and LTFS Index), and the content of the partition labels and use of MAM parameters. The data content (not the physical media) of the LTFS format shall be interchangeable among all data storage systems claiming conformance to t...view more

IEC/TR 62291:2009(E) specifies an application program interface (API) for reading and writing the files which conform to the Universal Disk Format (UDF) ® specification revision 2.00 developed by the Optical Storage Technology Association (OSTA) and its security extension. This second edition cancels and replaces the first edition, published in 2002, and constitutes a technical revision. The significant changes with respect to the first edition are the following:

ISO/IEC 22091:2002 specifies a lossless compression algorithm to reduce the number of 8-bit bytes required to represent data records and File Marks. The algorithm is known as Streaming Lossless Data Compression algorithm (SLDC). ISO/IEC 22091:2002 is based on ISO/IEC 15220. It extends that algorithm with the addition of control symbols that allow records of different sizes and compressibility, along with File Marks, to be efficiently encoded into an output stream which requires little or no addi...view more

ISO/IEC 13346 specifies a format and associated system requirements for volume and boot block recognition, volume structure, file structure and record structure for the interchange of information on media between users of information processing systems. The media shall be recorded as if the recording of sectors may be done in any order. Note 1 - The medium is not restricted to being of only one type; the type of medium may be either write once, or read only, or rewritable, or a combination of th...view more

This part of ISO/IEC 13346 specifies a format and associated system requirements for volume and boot block recognition by specifying: volume recognition; boot descriptors intended for use to bring a system to a known state; levels of medium interchange; requirements for the processes which are provided within information processing systems, to enable information to be interchanged between different systems; for this purpose, this part of ISO/IEC 13346 specifies the functions to be provided withi...view more

Consists of five parts; part 1 specifies references, definitions, notation and basic structures that apply to the other four parts.

Specifies a format and associated system requirements for record structure for the interchange of information on media between users of information processing systems by specifying record structures, the attributes of the records of a file and requirements for the processes to enable information to be interchanged between different systems.

Specifies the procedure to be followed by a registration authority in preparing, maintaining und publishing an international register of numeric identifiers allocated to the algorithms, excluding cryptographic ones. Describes in detail: registration authority; sponsoring authorities; registration, withdrawal, correction and revision procedure; early reservation of an identifier. An identifier registered in accordance with this standard serves as an identification of the algorithm associated with...view more

Specifies an algorithm for the reduction of the number of bits required to represent information. This process is known as data compression. The algorithm uses binary arithmetic coding and provides lossless compression and is intended for use in information interchange.

Specifies a lossless compression algorithm (DCLZ - Data Compression according to Lempel and Ziv) to reduce the number of bits required to represent information coded by means of 8-bit bytes. This algorithm is particularly useful when information has to be recorded on an interchangeable medium. Its use is not limited to this application.
